ERR_PACKAGE_PATH_NOT_EXPORTED on Node.js v24 — inconsistent vscode-jsonrpc subpath imports across dist files #891
Description
Node.js version: v24.13.0 (Active LTS)
SDK version: @github/copilot-sdk@0.1.32
Problem: The SDK's compiled dist files use two different import paths for vscode-jsonrpc:
- dist/session.js imports vscode-jsonrpc/node (no extension)
- dist/client.js imports vscode-jsonrpc/node.js (with extension)
Node.js v24's strict ESM resolver requires that subpath imports match exactly what the package's exports map declares. Since vscode-jsonrpc@8.2.1 (the SDK's pinned dependency) has no exports field at all, neither import path works under Node.js v24 strict ESM.
Attempting to override vscode-jsonrpc to 9.0.0-next.11 (which adds "./node" to exports) fixes session.js but breaks client.js since "./node.js" is not in the v9 exports map either.
Expected: Both dist files should use the same import path, and vscode-jsonrpc should be updated to a version with a proper exports map covering that path.
Workaround: Manual postinstall patch to add both "./node" and "./node.js" to vscode-jsonrpc's exports.
